 Scutelkim small, prothorax sparsely punctured. Two species mav 

 be separated: 



Lart^er, black, sparsely pubescent; thorax red, elytra tlensely punctured. 



ignicoUis. 



Smaller, red, elytra red with suture more or less black, legs more or less black; 

 elytral punctures coarse, distant .suturalis.

A very variable species. The legs may be red or black or anything- 

 between. The suture may not bear a trace of black or it may be more 

 or less black up to the form PearsaLi in which the apical third of the 

 P"dytra is black. The thorax is occasionally black. (PI. IV, f. 15.) 



OXOPLUS Li'c. 

 The species of this and following genera have the scutellum small 

 and acutely triangular. The species of Oxoplus are colored red and 

 black and differ from Tylosis by having the sides of prothorax obtusely 

 spinose and disk without callosities. The following synopsis by Dr. Geo. 

 H. Horn is extracted from Trans. Am. Knt. Soc. XII, May 1885. 



SYNOPSIS OF OXOPLUS. 



Thorax black, the tips of tubercles red; 

 Elytra very densely punctate, color black, the basal margin and the siile three- 

 fourths to apex red; body beneath at middle and entire abdomen red; apices of 



elytra (^ sinuately truncate, sutural angle rounded marginatus. 



Thorax red, the apical and basal margins somewhat narrowly black. 

 Abdomen red. 

 Elytra black, broadly margined with red at base which extends down the side 

 three-fourths to apex; surface densely rather finely punctate; apices sin- 

 uously truncate, sutural angle obtuse; body beneath red, sides of meso- and 



metasternum browner cruentus. 



l^lytra in great part red, a broad black band extending from the apex nearly two- 

 thirds to base; surface rather coarsely not densely punctured; apices trun- 

 cate, the sutural angle slightly prolonged; body beneath black, abdomen 



red ■ ' ■ corallinus. 



Abdomen and entire Ixuly beneath black.
